bears against the valve head 29 and holds the same against the collar32. The tip 34 is conical in form having a point 35 at the discharge endof the outlet it. The surface of the said tip recedes gradually from thesurface of the passageway it allowing the liquid passing through theoutlet to gradually expand and whereby the pressure of the liquid isgradually reduced to atmospheric pressure.

The upper end 36 of the valve stem 3| is threaded and is adapted toscrew into threads 46 in a plunger 31. This plunger has a portion 38which is slida'bly received within the bore l l and guides the upper endof the valve stem 3! for reciprocating movement within the body ill ofthe valve. The plunger 3'! has a groove 39 formed therein which isprovided with a cylindrical surface ll and a radial surface 42 connectedtherewith. In this groove is mounted an O-ring 43 similar to the O-ring26 and which firmlyengages the surface of the bor H and the surface 4iand which may engage the surface 42. The valve stem 3!, valve head 29and plunger 31 form a unit which has been termed a valve head assembly.

An inlet at is provided for the faucet which consists of a tube 35having a passageway 46 therein. Th said tube is brazed or soldered tothe body It and the passageway 45 communicated with an opening 41 in thesaidbody and brings the passageway 46 into communication with the bore 1l. The inlet 44 is located so that the opening i! is disposed betweenthe two O-rings 28 and 43. A compression coil spring at encircles thevalve stem 3! and is seated at one end against insert I l and at theother end against the plunger 3?. This spring serves to urge the valvehead 29 against the seat 28.

Mounted on the outer end of the body IE3 of the faucet is a cap 49 whichhas a spherical wall and a cylindrical wall 52 formed with a bore 5G.The cylindrical wall 52 has a flange 53 extending outwardly therefromand which is adapted to be engaged by a nut 54. Nut 54 is secured uponthreads 55 formed on the outer surface of the body I!) and serves toclamp the cap 49 firmly in position. The spherical wall 5| of cap 69 hasa socket 56 in the same and in which a ball cam member 51 is mounted foroscillatory movement. This cam member has threads 68 formed into thesame to receive the threaded end i of a screw 58. This screw passesthrough a bushing 59. Bushing 59 is mounted for sliding movement in anarcuate slot 6| which is formed in the wall 5i of cap 49. The screw 58also passes through a threaded fitting 62 which is formed with a collar63. The fitting 62 is adapted to be screwed into threads 64 formed uponthe interior of a handle or knob 65. When the handle 65 is screwed onthe fitting 62, the end of said handle engages collar 63 and the screw58 and the threaded portion of said fitting become concealed.

The cam 5? has a fiat surface 66 extending radially with respect to theaxis of the screw 58 and the valve stem 3! and another angular surface6! forming a corner 68 therebetween. Disposed within the interior of thecap 49 is a slide 89 having a cylindrical wall ll slidable along theinterior of the cylindrical wall 52 of said cap. The said slide furtherhas a radial wall 12 normally engaging the surface 66 of the cam member5'1; A compression coil spring 73 encircles an extension M formed on theupper end of the plunger 3? and is seated at one end against the portion38 of said plunger and at its other end against the under surface of.the radial Wall 12 of slide 69. This spring serves to hold the cam 51and handle 65 in the position shown in Fig. l and also urges the lip ofinsert ll against the shoulder 56. This spring is weaker than the springt8 so that said spring cannot unseat the valve head 29 from the valveseat 28. The slide 59, cam 57 and handle form the operating means forreciprocatingv the valve head assembly and unseating the valve head 29.

In assembling the parts of the faucet, the following is the procedure.Valve stem 3! is first inserted into th guide 2i and moved along thesame until valve head 29 reaches valve seat 23. Spring 58 is then placedabout the projecting end of the valve stem 3! and the threaded end 36 ofthe same screwed into the threads as in plunger 3'! until the saidspring is partially compressed, urging the valve head 2e against seat28. The O-rings 25 and 4-3 are next placed in the grooves 22 and 39. Thecam 53 is next placed in the cap etand nut 54 placed over the same. Thescrew 58 is then run through the fitting 62 and bushing 59. Said screwand bushing are then directed into the slot BI and the screw screwedinto the threads til in cam member 51. Thereafter the fitting $2 isscrewed into the threads 64 in handle 65. Thus two assemblies areformed, one including the insert II, the valve parts and the plunger 3?,and the other including the cap 63, handle and cam member 5?. Inapplying these assemblies to the faucet, the valve assembly is firstinserted into the more i i through the open end l2 thereof. The ring 26being smaller in diameter than the bore ll, fits freely in the same andthe assembly may be readily slid along said bore until the ring 63reaches the said bore. Pressure applied to the assembly forces the ring33 into bore ll causing the said ring to compress and to firmly engagethe surface of the bore H and the cylindrical surface ii of plunger 3?.Further movement of the assembly into the valve body causes ring 26 toenter the portion E5 of bore H and to become firmly engaged with thesurface of such portion of th bore and with the surface 23 of insert ll.Movement of the assembly is terminated when the lip 25 engages theshoulder 15. Spring F3 is next placed about the extension 14 of plunger1 and the slide placed over said spring. The second assembly includingcap 29, handle 65 and cam member 5? are next applied with the slide 69received within the bore 59 of said cap and with the flange 53 overlyingthe end of the body I!) of the faucet. Nut 54 is then screwed upon thethreads 55. This draws down the flange 53 against the end of th body itand compresses the spring l3. It will b noted that a slight amount orclearance is provided between the end of the extension '34 and the wallE2 of slide 59. This permits of improper seating of the lip 25 onshoulder l6 and compensates for irregularities in the construction ofthe faucet.

In operation, pressure in the interior of the faucet forces the twoO-rings 28 and d3 apart and against the surfaces 24 and 62. Thisprevents leakage of the liquid past the insert H and plunger 3i. Theengagement of the lip 25 on shoulder I6 is hence not relied on toprocure tightness. Spring 43 hence merely serves to urge the valve head29 against the seat 28, while spring 13 holds the handle 35 in theposition shown in Fig. 1. Upon movement of the handle 65 toward theleft, as noted in Fig. 1, bushing 59 travels along, slot 5! and thecorner 68 of cam member 51, engages the slide 69 and forces the .fvi vsame: downward and into engagement-with. the;

. extension 14'. This moves the plunger-3;! downwardly, unseating thevalve headldifrom engage;

ment with the seat 2.3 and. upeningrthefaucet.

During such movement, the O..-ring:43 slidesalong:

thev bore H beinglubricated. bythe liquid dispensed through the faucet.Whentheangular surface 61 of cam member. 5] reaches the positionshown inFig; 2,1the' faucet remains open.

Forthe: purpose of: cleaning orrepair, nut 54 can. be. removed the, cap.and handle. assembly comes .off. The valve; assembly can. then .be;

withdrawn .fr01n.the bore of the; faucet: body and theentireinteriorpof; thefaucetiis open..and .ex.--- posed, permitting ofcleaning the systemiiin;sac-

'Ihe advantages-of my inyentionaremanifest. The faucet-can beconstructed atran extremelyeconomical. cost. due to. the fact that. all:of the metalgparts may be-constructed on. aiscrew'machine. The valveassembly may be: removed. from the faucet body as a unit withoutdistunbingthe.

Should particles offoreign'matter become lodgedupon the shoulder lficf'the body, the samelwill not interferewithsuccessful operation of the device since tightness between the valveassembly and body is not procured through this connection.
